Spray Pump Control in Thermal Container Treatment Standby
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thermal container treatment apparatuses, such as coolers, warmers, or pasteurizers, face inefficiencies in electrical and thermal energy consumption during standby and normal operating modes due to continuous dispensing of treatment medium.
Innovation Solution
Implementing a control apparatus that manages pump operation at rated power during normal operation and reduced power or standby, utilizing temperature sensors and bypass systems to conserve energy and maintain operational readiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump operates continuously at rated power to dispense treatment medium, then the thermal container treatment apparatus maintains operational readiness, but electrical and thermal energy consumption increases
Solution Approach 1:
The control apparatus switches the pump between operating states (on/off or reduced power) based on whether containers are present in the treatment zone. During standby operation with no containers, the pump is turned off or operates at reduced power. When containers are detected, the pump operates at rated power to dispense treatment medium, thus creating a periodic action pattern that matches production demand.
Solution Approach 2:
The pump's power output is dynamically adjusted based on operational conditions. The control apparatus enables the pump to operate at rated power during normal operation and at reduced power or off during standby, making the system adaptable to varying production requirements and minimizing energy consumption when full capacity is not needed.
2Use of energy by moving object
If the pump operates at reduced rated power during standby, then electrical energy consumption decreases, but treatment medium dispensing capability is reduced
Solution Approach 1:
The system uses periodic action by switching the pump between full power operation (when containers are present) and reduced power or off state (during standby). This ensures that treatment medium dispensing capability is maintained at full level when needed, while minimizing energy consumption during periods when no treatment is required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces thermal and electrical energy consumption by minimizing treatment medium dispensing during standby, while ensuring rapid operational readiness through controlled temperature management.
Implementation Method 1
A temperature sensor is provided to measure the temperature of the treatment medium
Implementation Method 2
a pump is provided in the line connection... operate the pump at a rated power for dispensing treatment medium by the spraying apparatus
Implementation Method 3
a treatment zone with a spraying apparatus for dispensing treatment medium to containers... there is no atomization of the treatment medium when it is dispensed using the spraying apparatus
Implementation Method 4
By not operating the pump or by operating the pump at a reduced rated power, thermal energy consumption can be reduced, since there is no atomization of the treatment medium when it is dispensed using the spraying apparatus

AI summary
A thermal container treatment apparatus comprising a conveying apparatus for containers, a treatment zone with a spraying apparatus for dispensing treatment medium to containers, a tank for collecting and providing treatment medium and a line connection between the tank and the spraying apparatus, wherein a pump is provided in the line connection. A temperature sensor is provided in the tank below a filling level of the treatment medium. The thermal container treatment apparatus comprises a control apparatus which is configured to operate the pump at a rated power for dispensing treatment medium by the spraying apparatus during normal operation in the treatment zone and not to operate the pump during standby operation in the treatment zone or to operate the pump at a reduced rated power without treatment medium being able to be dispensed by the spraying apparatus.
